SUB JECT-SQUARING GAGE.

Application filed November 1, 1905.

of New Jersey, have invented a new and useful Improvement inSubject-Squaring Gages,

in the plane of the line 4-4 of Fig. 1.

of which the following is a specification.

My invention relates to a subject squaring gage for determining the linealong which the plate and its supporting block are to be cut to make theborder line of the plate harmonize with the position line of the subjectdelineated on the plate.

In electrotype and photo-engraving plates from which printing is to bedone it frequently happens that the plate containing the subject to beprinted will 'besecured to its supporting block with the position of thesubject out of harmony with the border line of the plate, that is,oblique to the border line when it should be parallel thereto or atright angles thereto.

My present invention is directed to a gage which may be readilymanipulated to indicate on the plate the line along which the plate andits supporting block may be cut to true or square it as it is commonlycalled, with respect to the subject.

In the accompanying drawings, Figure 1 is a top plan view of a portionof a tool showing the gage supported thereon in position for use andalso showing a plate thereon with the subject delineated on the plate,in the present instance a flag and staff, out of true with respect tothe margin of the plate. In this view the horizontally rocking member ofthe gage is shown in position at right angles to the longitudinallymovable and vertically rocking member Fig. 2 is a similar view showingthe horizontally rocking member of the gage rocked to bring the plate tobe cut into position with its position line, in the present instance theflag staff, parallel with the other member of the gage for indicatingthe line along which the plate is to be cut to true it with respect tothe subject. Fig. 3 is a view of the same in side elevation, the partsoccupying the positions which they assume in Fig. 1.

ing the backward swing of the horizontally rocking member. I Fig. 8 is atop plan view in detail of the horizontally rocking member of the gage,and Fig. 9 is a face view of the same.

1 represents a table which may be the table of the sawing machine orother suitable cutter to which the gage is to be applied. This table 1is provided with a dovetailed or undercut groove 2 extendinglongitudinally along its face in which a bar 3 fits and slides the bar 3forming a support for the gage as a whole.

The gage proper comprises a supporting track in which one member of thegage rocks horizontally and along which another member of the gageslides longitudinally, the second member of the gage'being furtherprovided with an arm at right angles to its stock and hinged to itsstock to swing in a vertical plane. The said supporting track is denotedby 4 and extends transversely across the table 1. The said track isprovided with a stem 5 formed integral with or rigidly secured to thetrack, the said stem being fitted to rest in close contact with the topof the bar 3 to which it is removably secured, in the present instanceby means of screws 6 and 7. The track is held by means of the stem 5, ashort distance above the plane of the table 1 and to its underside thereis pivotally secured the horizontally rocking member 8 of the gage. Themember 8 is conveniently made of a general T-shape in cross section asclearly shown in Figs. 4, 5 and 6. The web portion 9 extendingunderneath the track 4 where it is provided near one end with a boss 10through which the pivot screw 11, extends into the underside of thetrack 4. To give the member 8 additional bearing in its swingingmovement and at the same time leave it free from contact with the trackand table throughout the greater portion of its length, I provide itwith a bearing boss 12 intermediate of its pivotal connection and itsend furthest therefrom, the intention being that the member 8 shallswing into and out of position between the track and the face of thetable with the boss 12 in sliding contact with the underside of thetrack. The face of the member 8 is upright as shown and of suffioientdepth to insure a firm rest for the side of the block which engages it.In the top of the track 4 there is formed a dovetailed or undercutgroove 13 in which the stock 14 of the other member of the gage isreceived with a longitudinally sliding fit. The stock 14 has hingedthereto an arm 15, the arm 15 extending at right angles to the stock andas here shown at right angles to the longitudinal axis of the track 4.The arm 15 is pivoted to the stock 14 by means of a socket piece 16 madefast to the arm 15 and a pintle 17 extending through the socket piece 16and bearing in brackets 18 and 19 uprising from the stock 14. The stock14 is locked in its longitudinally sliding adjustment in the track 4 bymeans of a set screw 20 tapped therein in position to be screwed intoand out of engagement with the bottom of the undercut groove 13.

The rocking member 8 is rocked by means of a thumb screw 21 extendingtransversely through and seated in-the track 4, the free end of saidscrew bearing against the back of the upright head or face of the saidmember, the said screw working in opposition to a retracting spring 22located beneath the track and tending to draw the free end of the member8 back against the end of the screw 21.

For the purpose of limiting the backward swinging of the member 8 underthe impulse of the spring 22 at the point where its face will be atright angles to the arm 15, I locate a stop 23 in the track 4 and permitit to project below the stock sufliciently to engage the web 9 of themember 8 when the member 8 has reached a position at right angles to thearm 15. At the same time it is desirable that the member 8 should insome instances.

round projection 24, see Fig. 5, and provide' the stop with an operatinghandle 26 so that when it is desired to bring the member 8 back to aposition just at right angles to the arm 15, the stop 23 may be swunginto the position Fig. 1, with its lever 26 against the pin 27 and whenit is desired to swing the member 8 back of this position at rightangles to the arm 15, the stop 23 may be turned half round by swingingits lever 26 against the pin 28, thereby throwing the projection 24 offto the'opposite side of the stop or side furthest from the member 8 andpermitting the latter to swing back of the position at right angles tothe arm 15. In extreme cases where it is desirable to swing the armfurther than allowed by turning the stop half round, the said stop 23may be unscrewed a distance sufiicient to withdraw the projection 24from the path of the member 8, permitting the latter to swing stillfurther back of its position perpendicular to the arm 15.

In operation, assume a block 29 with plate 30 fast thereon and bearingan emblem consisting of a staff 31 with flag 32 to be in hand with aview of cutting the plate or block to make its sides and endsrespectively parallel to the longitudinal axis of the staff 31 and atright angles to said axis. The plate having been placed in the positionshown in Fig. 1, it is at once observed that the axis 'of the staff 31is oblique to the margin of the plate and having placed the block withplate thereon against the face of the member 8 with the arm 15 inproximity to the staif at one end, the screw 21 may be turned, rockingthe member 8 into the position shown in Fig. 2, thereby tilting theblock 29 and plate thereon into a position to bring the longitudinalaxis of the staff 31 parallel to the edge of the arm 15. This havingbeen done, the block may be out along the line indicated at the outeredge of the arm 15 or the block may be slid inwardly until the outeredge of the arm 15 reaches the outer edge of the block at one corner anda line may then be drawn along the edge of the arm 15 to indicate theline of cut. The plate having been cut or lined and cut parallel with anedge of the arm 15, for instance by sliding the table 1 along'intocontact with a suitable saw or other cutter not shown, the same formingno part of my present invention, the block 29 with plate thereon maythen be placed with its out side against the face of the member 8 andthe latter swung back into position at right angles to the arm 15. Thiswill bring the end of the block and plate in position to be cut at rightangles to the position line, viz: the longitudinal axis of the staff 31and the block and plate may then be out along this line guided by theeye, the line and the gage arm 15, or a line may be drawn with the arm15 as a guide and the arm 15 may then be swung back out of the way andthe block out along this line. In like manner the plate may be turnedwith the last cut end against the face of the member 8 and the otherside out parallel with the first cut and then inmoved away from andtoward the track 4 by sliding its stock 14 along the track and lockingit in position by means of the set screw 20.

The structure as a whole is simple and provides for the rapid andaccurate squaring of the plate .with respect to the subject whatever bethe size and condition of the plate within limits commonly encountered.

What I claim as my invention is:

1. A subject squaring gage comprisin a suitable support, a horizontallyrocka le member located on one face of the support,

a horizontally sliding member located on the opposite side of thesupport and means for positively arresting the movement of the saidrockable member with reference to the sliding member.

2. A subject squaring gage comprising a horizontally rockable member, amember provided with a vertically rockable arm and means for adjustingthe position of the horizontally rockable member at different angles tothe vertically rockable arm.

5. A subject squaring gage comprising a track provided with means forspacing it from the table, a horizontally rockable member pivoted belowthe track, a horizontally sliding member mounted in the track and meansfor adjusting the members with relation to each other.

'6. 'A subject squaring gage comprising a track provided with means forspacing. it from the table, a horizontally rockable member pivoted nearone end to the underside of the track and provided with a bearingintermediate of its pivotal point and end for preventing vibration, amember mounted in the track in position to co-act with the horizontallyrockable member and means for adjusting the members with relation to oneanother.

7. A subject squaring gage comprising a track provided with means forspacing it from the table, a horizontally rockable member pivoted to theunderside of the track, a retracting spring engaged with said member andwith the track, a screw for rocking the said member against the tensionof the spring and a gage member mounted in the track in position tocoact with the aforesaid rockable member.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two witnesses, this 12th day of October 1905.
